MUSIC-LEAF TURNER.

Specification of Letters latent.

Patented Jan. 5, 1915.

Application filed June 3, 1914. Serial No. 842,702.

T 0 all whom it may concern Be it known that I, J osnrrr HARTMAN, a citizen of the United States, residing at Apponaug, in the county of Kent and State of Rhode Island, have invented new and useful Improvements in Music-Leaf Turners, of which the following is a specification.

This invention is an improved music leaf turner, the object of the invention being to provide an improved music leaf turner which has a stand to which it is detachably connected, the music leaf turner being adapted to be used either on the stand or detached therefrom or arranged on a piano or other support; another object being to provide an improved music leaf turner which may be compactly folded when not in use and which may be very easily operated.

The invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings :Figure l is a front elevation of my improved music leaf turner showing the same on the supporting stand and arranged for operation by the foot. Fig. 2 is a rear elevation of the same when detached from the stand and adapted to be placed on a piano or other support. Figs. 3456 are detail views.

In the embodiment of my invention I provide a supporting stand 1 which has a base 2 to which tripod legs 3 are pivotally connected at their upper ends as at 4 so that they may be either extended or folded as desired. A tubular standard member 5 rises from the center of the base and has a set screw 6 near its upper end. A sleeve 7 is vertically slidable on the standard member 5 and may be secured thereto in adjusted position by a set screw 8. Links 9 are pivotally connected to the sleeve and to the tripod legs 3 thereby adapting the legs to be placed in folded position as will be understood.

A tubular standard member 10 is telescopically arranged in the standard member 5, may be engaged and secured in adjusted position by the set screw 6 and has a set screw 11. A standard member 12 is telescopically fitted in the standard member 10 and may be secured therein in adjusted position by the screw 11. It will be understood that by telescoping the standard and folding the legs 3 the stand may be easily disposed in very compact condition.

A standai l 13 is provided at its lower end on its rear side with a socket 14 for there ception of the upper end of the standard member 12 of the stand so that the said standard 13 may be detachably secured on the stand. A pair of supporting arms 15 have their inner ends pivotally connected to the lower portion of the standard 13 as at 16. These supporting arms are adapted to be extended horizontally from the lower end of the standard 13 in opposite directions or to be folded up parallel therewith. Each supporting arm is provided with a foot 17 to bear on a piano or other support and coact with the lower end of the standard 13 in holding the music leaf turner on the piano or other support when detached from the stand 1. One of the arms 15 is provided on its front side with a semi-tubular clip 18 to engage the lower side of one leaf of the music.

Arms 19 to bear against the rear side of the music are pivotally connected at their inner ends to the standard 13 as at 20 and are connected to the arms 15 by links 21, said links being pivctally connected to the arms 19 as at 22 and to the arms 15 as at 23. Each arm 19 is also connected to its link 21 by means of a pair of links 2-1 which are pivotally connected together as at 25 and are also pivoted to the arms 19 and links 21 as at 26-27. Hence the arms 19 and their links may also be folded, together with the arms 15 parallel with the standard 13 to dispose the music leaf turner compactly when not in use or may be extended outwardly therefrom for use, as shown.

A vertical shaft 28 is mounted in bearings 29 on the front side of the standard 13 and is provided at a suitable point with a beveled gear 30 one side of which extends through an opening in the standard, the front side of the said beveled gear being covered by a casing 31 with which the standard 13 is provided. This shaft is provided at its upper and lower ends with music leaf turning arms 3233. The arm 32 comprises an inner member 3-1 and a substantially semi-tubular outer member 35 the channel of which is on its lower side. The member 35 is pivoted at 36 to the member 34 and the latter has a catch 37 to engage and support the member 35 in horizontal position.

The arm 33 has an inner member 38 pivoted as at 40 and when in horizontal position rests on a support 41 with which the member 38 is provided. The channel of the member 39 is on its upper side and the said member 39 is made of spring metal and acts as a clip to engage the lower side of one leaf of the music, the upper side thereof being engaged by the member 35.

A segment gear 42 is mounted on the rear side of the standard 13 as at 43 and has an arm 44. Said segment gear engages the gear and is provided at one side with a hook 45 to which is attached one end of said spring 46, the other end of said spring being attached to the standard 13.

It will be understood that by turning the segment gear in one direction against the tension of the spring 46 it will by coaction with the gear 30 turn the shaft 28 through half a revolution and thereby cause the arms 32-33 to move with the said shaft and turn the leaf of the music carried by said arms. When the said segment gear 42 is released the spring 46 will move the said gear rapidly in the reverse direction thereby reversely turn the leaf carried by the arms The movements of the segment gear 42 are rapid so that the music leaf will be turned rapidly in one direction or the other as desired. To look the segment gear 42 when turned against the resistance of the spring 46 the standard 13 is provided with a spring catch 47 which engages the upper side of the arm 44 as said arm passes downwardly over said spring catch. By giving the arm 44 a slight lateral movement, it is released from the catch 47.

A handle 48 is detachably connected to the arm 44 when the music leaf turner is to be operated by hand,said handle being pivotally connected to a coupling 49 which is slidable on the arm 44. When the music leaf turner is to be operated by foot, I provide in place of the handle'48 a vertically disposed connecting rod 50 comprising a pair of sections 5l52 the section 51 being pivoted to the arm The member 52 has a longitudinal slot 53 therein which is engaged by a set screw 54 that connects said member to the member 51. The lower end of the member 52 is pivotally connected to a treadle 55 which is pivotally connected to one of the tripod legs 3 of the foot.

Having thus described my invention, I claim In a music leaf turner a standard, supporting arms pivotally connected to the lower portion of the standard and adapted to be extended out therefrom or folded up against the same, said supporting arms having feet, upper arms pivotally connected to the standard, links connecting the upper arms and the supporting arms and movable therewith when the said arms are folded or extended, a shaft mounted in bearings on the standard and having a gear, jointed foldable music leaf carrying arms attached to said shaft to turn therewith, a segment gear mounted on the standard and engaging the first named gear and means to operate the segment gear.

In testimony whereof I aiiix my signature in presence of two witnesses.

JOSEPH HARTMAN.
